Safety Precautions
• Be sure to turn off power before mounting, removal, wiring, maintenance and inspection. Otherwise, electric shock or fire could
occur.
• Be sure to use timers within rated specification values. Otherwise,
electric shock or fire may occur.
• Be sure to use wires to meet voltage and current requirements
and tighten M3.5 terminal screws to a tightening torque of 1.0 to
1.3 N•m. Be sure to solder the terminals correctly. Loose terminal screws or incomplete soldering may cause abnormal heat and
fire.

The time range is calibrated at its maximum time scale, therefore
it is desirable to use the timer at a setting as close to its maximum
time scale as possible for accurate time delay. For a more accurate
time delay, adjust the control knob by measuring the operating time
with a watch before application.
On the GT5Y timers, a desired time range can be selected using
the time range selectors on the side surface. Turn the multiplier and
time unit selectors using a flat screwdriver until they click.
Switching an inductive load generates a counter-electromotive force
in the coil. The counter emf will cause arcing, which may shorten the
contact life. Application of a protection circuit is recommended for
contact protection.

Rest Time
When turning power off after time-out, allow a rest time of 0.1 sec,
and during operation, 1 sec at least.

Since DC types are designed to operate on DC power containing
10% or less ripple, insert a smoothing circuit when using a rectified
AC power to operate DC type timers.

Continuous Energizing
Continuous energizing for a long period of time may damage the
electrical characteristics of the timer because of internal heating.
Use an additional relay to the output circuit and refrain from continuous energizing of the timer.

Use of External Input (GT5P-P Only)
1. Do not apply voltage to external input terminals 3 and 4. Be sure
not to connect external inputs to other terminals because the
internal circuit may be damaged.
2. Use reliable mechanical contacts capable of switching approximately 22V DC, 1 mA to close input terminals 3 and 4.
(Closed: 1 kΩ maximum, Open: 100 kΩ minimum) The input
terminals should not be connected to a ground wire of other devices.
3. Do not install input lines in parallel with high-voltage or motor
lines. Use shielded wires or separate conduit for input lines, and
make the input lines as short as possible.
Load Current
The rated current of the contact (or control output) should not be exceeded. Especially for inductive, capacitive, and incandescent lamp
loads, the inrush current as large as a few to several tens times the
rated current may cause welded contacts and other troubles. The
amount of inrush current as well as steady-state current must be
taken into consideration.
When performing an insulation resistance or dielectric strength test
on control panels containing timers, make sure that the dielectric
strength of the timer is not exceeded. In case the dielectric strength
is exceeded, remove the timers from the panels.

Operating Environment
• Temperature and Humidity
Use the timer within the operating temperature and operating humidity ranges and prevent freezing and condensation. After storing below the operation temperature, leave the timer at room temperature for a sufficient period of time before use.
• Environment
Prevent a corrosive gas such as sulfurous or ammonia gas, organic solvents (alcohol, benzine, thinner, etc.), strong alkaline
substances or strong acids from touching to the timer, and do not
use the timer in such an environment. Keep the timer from water
splashes or steam.
• Vibration and Shock
Since excessive vibrations or shocks cause the output contacts
to open, the timer should be used within the operating extremes
of vibration and shock resistance. Use of hold-down springs is
recommended for secure mounting on sockets.
Others
• Use a mechanical-contact switch or relay to supply power to the
time.
• When driving the timer using a solid-state output device such as
two-wire proximity switch, photoelectric switch or solid-state relay
directly, malfunction may be caused by a leakage current from the
solid-state device. Be sure to check thoroughly before using.
• Since AC types (such as A100 and A200) comprise a capacitive
load, the SSR dielectric strength should be two or more times as
large as the power voltage when switching the timer power using
an SSR.
• To make a sequence circuit by connecting timer and relay, check
the timer operation sufficiently in consideration of the reset time
of the timer.
